Tocll whom it-may concern:

Be it known that I, DANIEL B. I)ANIELS ON,

residing iii-Milwaukee; in the county of Milwaukee and State of Wisconsin, have invent ed new and useful Improvements in Column Construction, of which the following is a description, reference being had to the accompanying drawings, which-are a part of this specification: I

This invention has for its ob ect to provide an improved column construction for use 111 building edifices, beamless floor and roof constructions and the like, and has for its object to: provide a column of iron or steel fra1nework with a concrete body of cement and other matter used in reinforced concrete construction work, which column will be strong,

durable and simple to construct.

With the above and other objects in View theinvention consists in thecolumn construction herein claimed, its parts and combinations of parts and all equivalents.

Referring to the accompanying drawings in which like. characters of reference indicate the saine'parts'in different views; Figure 1 is aplan-view of aframework of a pair of columnsmade in accordance-withthis invention; Fig. 2 is a side elevation thereof partly iii-central section; and, Fig. 3 is a transverse sectional viewthereof on the' plane of line 3.-3 Of 2.

' In -these drawings '5 represents a series of verticalrods arranged in a circular-manner 3 -to;form .the main frame-of'a column of annu-- I preferably inl multi Ies of three, so that ..t1e. wires 6 may eachbmd together three of 'lar or other approved section, these rods .be-

-thever-ticfs'tl rods in such a manner that they take theform-ofisosceles triangles. The tie .wires cameraman the differentsets ofver tical :rods and are arranged. at such intervals throughout the length of the column as to complete. a well braced skeleton frame to re- .c'eive' a filling 7 of any concrete mass which is molded thereon ina-desirable manner.

-;Near=the top and base of the column the frame is provided with rods 8 bent 'toform 1 circular frames which are successively larger as they'appr'oach the end of the column con'-.

'stituting a support for the base or the capital of: the column.

'On' the top of the column some of the vertical rods are ,bent outwardly,and radially from-the .airisof "the column and slightly downwardlfrom the end ofthe column to form a, con1cal support and on this support are attached in any desirable manner a series -of square frames 9. of different sizes, the

largestframe being firstiiiountcd on the support of outwardly bent rods, thcmthc next size frame'beingmountcd thereon. at oneeighth turn with. relation thereto with its corners overlapping the sides of the larger frame, and the succeeding frames are placed in similar arrangement with each other and with the aforementioned frames so as to build up a conical framework on the support, the frames being successively smaller as they approach the end of the column. This framework is to support the floor or roof above or to receive the foundation if at the foot of the column.

The largest square frame 9 of each column is'connected with the corresponding square frame of each of the columns adjacent .;,to it by connecting bars 10 whichstart from one cornerofthe frame 9 of one columnand pass over that column and. the diagonally opposite corner of said square frame to the next column where it connects with the near corner of the corresponding square frame.

Thus each of the large square frames 9 has a pair of connecting bars '10 crossing-it on each -of its diagonals and each'of said square frames is connected with each jadjacent square frame by two of the connecting bars, forming a rigid means for tying together all of the columns. Such of the vertical rods 5as are not bent over to .form the conical support above referred to, preferably those which rise between the pairs of connecting bars. 10, as shown in the drawings,qc'ontinue upwardly above the-colurhnto constitute a means for locating the corresponding vertical rods for the column on the next floor, and thus assure the columns on the. different floors being in true vertical alinement.

Upon the column-construction above described ma be built the cement floor or roof in the usua manner.

By means of this construction the stress upon the column is evenly distributed throughout by reason of the triangular tic Wires connecting the vertical rods, and the frames of the supports being Without curves to yield are capable of sustaining a maximum stress.

What I claim as my invention 1s; 1, A column construction, comprising, a

series ofvertical rods arranged'in circular.

formation, tie wires connecting the-vertical rods and forming a framework therewith, circular metalframes at the end of the column increasing in size asthey approach the end of the column, and a concrete body formed within and upon the framework.

- 2. A column; construction, comprising a framework formed of a series of vertical rods arranged in circular formation, tie wires ofisosce estriangular shape connecting difi erent. sets of vertical rods at intervals and forming a framework therewith, circular metal frames'at the end of the column increasing in size as they ap roach the end of the column, and a concrete body formed within and upon the framework.

3. A column, comrising a framework of vertical rods arrange in circular formation,

tie wires connecting different sets of vertical rods at intervals and forming a framework therewith, circular metal frames near the end of the column, a series of square metal frames surrounding the vertical rods and being of successively smaller size and each differing in position by an eighth of a turn from the ad acent square frames,-the vertical rods being bent outwardly and radially from the axis of the column to engage the square frames, and a concrete framework. A

body formed on the 4.;A column, comprising a framework formed of a series of vertical rods. arranged in circular formation, tie wires connecting the vertical rods together, the vertical rods being bent radially to the axis of-the column and downwardly from the end of the column, a

7 series of square metal frames secured on the outwardly bent ends of the vertical bars and" being of successively smaller size and each having its corners overlapping and bearing upon the sides of the next square frame, connecting rods connecting the largest square frames'of adjacent columns each assing diagonally across one of said s uare ames and secured to the near corner 0 the next square.

frame, and a concrete body formed on the.

framework.

5. A column, comprising a framework formed of a series of vertical rods arranged in circular formation, tie wires connecting the vertical rods at intervals, circular metal frames at the, end of the column, the ends of the vertical bars being bent outwardly and radially and slightly inclined, square metal frames of, different sizes mounted on said bent ends of the vertical rods and arranged in the order of their size with the corners of each frame overlapping and engaging the sides of the next larger frame, and connecting bars connecting the square frames of each column with the square frames of adjacent columns and each passing diagonally across one square. frame and connected to the near corner of the next square frame, some of said vertlcal rods passing through the square metal frames and between the diagonally R.
